Tipsformowingconditions:
Whenmowinginareaswithsandysoil,use lowliftbladesonthecuttingdeckandhigher cuttingheightstominimizewearontheblower components.
Whenmowinginwetconditions,suchasjustafter arainorinheavydew ,uselowliftbladesonthe cuttingdecktominimizepluggingoftheblower.
Maintainingagroundspeedthatdoesnotpull downtheengineRPMwillallowforthehighest productivityandbestqualityofcut.Boggingthe engineRPMdownbygoingtoofastwillcause pluggingandqualityofcutissues.
Whenthehoppergetsfull,thesoundofthe blowerwillchangeandtherewillbeslight blowoutfromthefrontrightcornerofthedeck. Emptyingthehopperatthispointwillminimize thepotentialforthetubetoplug.
ForunitsbelowSerialNumber600,000: Anti-blowoutkitsareavailableforleafcollection. Theyhelptoprevent“chasing”theleaves.To reduce“plowing”leaves,raisethedeckslightly.
